Description
Control valves CV 2x0 are single-seated valves designed for regulation of process medium flow. In regard of a great variety of usable actuators, the valves are suitable for regulation at low as well as high differential pressures in a diversity of operating conditions. Flow characteristics, Kvs values and leakage rates correspond to international standards.
Valves CV 2x0 are especially designed for electromechanic and pneumatic actuators of the following producers: Auma, Schiebel, Rotork and EMG - Drehmo, Auma, Schiebel, Rotork a EMG - Drehmo, Honeywell, Fisher - Rosemount and SPA Praha.

Application
These valves have a wide range of application in heating, ventilation, power generation and chemical processing industries. Valve body can be optionally made of cast steel, cast CrMoV steel and stainless steel.

Process media
Valves series CV 2x0 are designed for regulation of flow and pressure of liquids, gases, vapours and other media compatible with material of the valve inner parts. To ensure reliable regulation, producer recommends to pipe a strainer in front of the valve into pipeline or ensure the process medium to be without any abrasive additions or impurities.
